High-Stress Abrasion and Impact-Abrasion Testing of Wear Resistant Steels

Energy can be saved by enhancing the service life of machinery and by designing lighter units. These design changes enable, for example, lower fuel consumption and larger payloads. The implementation of this kind of solutions, however, requires development of better wear resistant materials. In this...
